BURNER FOR BURNING RICH GASES, ESPECIALLY ACETYLENE GAS.

SPECIFICATION forming part of Letters Patent No. 596,144, dated December28, 1897.

Application filed April 29, 189 '7.

To ail whom it may concern;

Be it known that I, EDWARD J. DOLAN, of Philadelphia, in the State ofPennsylvania, have invented a new and useful Improvement in Burners forBurning Rich Gases, especially Acetylene Gas, of which the following isa full, true, and exact description, reference being had to theaccompanying drawings.

This invention relates to an improved burner for burning gases rich inhydrocarbon, and especially for burning acetylene gas, its object beingto produce practically a smokeless flame and a burner which in practicewill not become choked or clogged by deposited carbon. In accomplishingthis result I mingle or surround the gas to be consumed with a suitableamount of air before such gas is brought to the kindling temperature orpoint of combustion.

In the class of burners in which two jets of gas are caused to impingeagainst each other a limitation in the size of the flame arises byreason of the fact that, as ordinarily con structed, an excess ofescaping gas produces an irregular or smoky flame, especially whenacetylene gas is burned. If the angle of the jets to each other isacute, this limitation is met earlier than when the angle of the jetsapproaches parallelism, but in the latter case there is a downward bodyor fold of the flame produced which prevents the proper formation of theflame and produces irregularity and smoke.

By my present invention I have added to the two previously-known jets,inclined toward each other at an angle, a third jet which meets thesetwo at or about their point of intersection and forces the flame upwardand thereby prevents the formation of the fold to which I have abovereferred.

My invention will be readily understood from the accompanying drawings,in which similar letters of reference refer to similar parts, and inwhich Figure 1 represents a vertical elevation of my improved burner inpart broken away; Fig. 2, a vertical section at right angles to Fig. l,and Fig. 3 a plan of my improved burner.

Serial No. 634,376. (No model.)

A represents the ordinary pillar, and B the burner-block. This block maybe made of any of the materials ordinarily employed for makinggas-burners. It is provided with two small gas jets or channels 0,inclined at such angle to each other as that these jets meet in the cupshaped chamber D. An annular channel E encircles the burner-block and ispierced by the burner-orifices O. The burnerorifices are bored out tolarger diameter, as at F, beyond the annular channel E, and airsurrounds the gas passing through the channels F, but the flame is notformed until the gas and air escape into the cup D. A

V vertical channel G is cut through the burnerblock and enters at thebottom of a horizontal channel H,which intersects the cup-shaped openingD, as plainly shown in Figs. 2 and 3. This channel furnishes anair-supply to the gas passing upward through the channel G before itmeets the intersecting gas-jets escaping from the tubular openings F F.The effect of this third jet is to force upward the intersectinggas-jets. This therefore enables me to burn in this burner a much largeramount of acetylene'gas than would be the case if the third vertical jetwas not employed.

The operation of this burner is to cause to meet at the same point threejets of gas and each of, those jets is itself surrounded and partlymingled with air before reaching the point of combustion. For somepurposes this air-mixing device is not essential.

In practical operation this burner produces a regularly-shaped flame,without smoke and without clogging, and it can burn a muchlarger volumeof acetylene gas under these conditions than the burners at present inuse.

It is obvious that my invention may be in part utilized without thethird jet.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination in a gas-burner of two jets inclined toward eachother and meeting at the point of combustion, and a third jet located inthe same plane as the first two jets, in the bottom of a slot at rightangles to the plane of said two jets, said third jet intersecting themat their point of junction, each of said jets being provided with anindependent air-mixer bringing air in contact with the gas beforereaching the point of combustion, substantially as described.

2. The combination in a burner of two jets inclined toward each otherand located in the same burner-block with an air-mixing deviceconnecting with each of said jets, substantially as described.

3. The combination of the two jets 0 0,10- cated in the burner-block B,and the air-mixing openings E E, cut in said block, substantially asdescribed.

4. The combination of the two jets O C, located in the burner-block B,with the converging channels F F, carrying the mingled gas and airtoward the point of combustion, substantially as described.

5. The combination in the same burnerblock of two inclined gas-channelsC O, the
